This invention relates to improvements in warp beams and it is the general object of the invention to provide means associated with improved warp head clamp means to hold the warp ends on the beam. I

In my co-pending application Serial No. 582,551, filed March 13, 1945, I have set forth a beam'so constructed that the pressure of the warp threads forces a sleeve or the like against the beam barrel to prevent longitudinal slippage. The warp head is connected to the sleeve and is thus held in position on the, beam barrel by the very forces which tend to move the head along the barrel. Preparatory to the warp winding operation it is customary to attach the warp threads to the beam so that rotation of the beam will draw the warp threadsfrom a creel. It is an important object of my present invention to construct the aforesaid sleeve with warp holding lips or projections which hold the warp threads at the start of the winding operation; I

In order that the sleeve may be compressible or deformable for the purpose of being forced against the beam barrel one longitudinal slot and it is another object of my invention to have the warp holding lipsor projections extend from the sleeve into the slot, thereby permitting the warp threads to be held between the lips and the beam barrel. The in ward force exerted by the warp threads tends to bend the lips toward the barrel to insure tight holding f the warp ends. 7 Where the sleeve is made of a metal having an appreciable thickness itma'y be desirable to use a shell surrounding the barrel and extending between the warp heads. It is a further object of my invention to construct this shell with a longitudinal slot into which warp holding lips or projections extend; In order that the lips on the sleeves and the shell may be aligned it is a further object of the invention to provide the shell and sleeves with overlapping parts which prevent substantial relative angular movement around the beam barrel. Even in those instances where the sleeves are made of thin sheet metal it would still be desirable to have holding lips or th like for the intermediate part of the beam and the aforesaid shell is therefore not limited to use with sleeves having thick walls.

With these and other objects in view which will appear as the description proceeds, my invention resides in the combination and arrangement of parts hereinafter described and set forth.

In the accompanying drawing, wherein a convenient embodiment of my invention is set forth,

in which the holding lips or projections catch. the warp threads. I I p Referring to Fig. 1, the beam designated generally at B has a cylindrical barrel l0 extending throughout the length thereof. Right and left beam headsl-I and H" are mounted on the barrel in such manner that they can be adjusted therealong to vary the width of the warp space between them. The warp heads and parts attached thereto are similar and a description for one of them will sufiice for both.

The head H is formed with a flange II having a warp engaging surface l2 and a hub I3. A sleeve l5 made of thin sheet metal surrounds and closely fits the barrel l0 and passes through the bore Hiof the hub I3. The outerend of'the sleeve is turned up to form a flange I! which can be secured in any approved manner to the hub [3. The sleeve may be driven into the bore in the hub so that the latter and united. v

The sleeve has front and back longitudinal slots 20 and 2|, respectively, which define upper and lower sections 22 and 23, respectively, extending along the barrel and compressible byreason of the slots against the barrel by the pressure of the warp wound on the beam. As shown more clearly in Figs. '1 and v3 a series of lips or projections 25 are integral with the section 23 and extend into and part way across the slot 20. As shown in Fig. 5 these lips are spaced slightly from the barrel to define a notch 26 into which the warp threads W may be held. The sleeve sections and lips are somewhat resilient and can be pressed toward the barrel ill by the warp threads.

Extending along the barrel between the sleeves I5 is an intermediate shell 30 which in the present instance may be formed with a single slot 3| into which extend lips 32 similar to lips 25. The shell 30 has end teeth 33 which enter notches 34 in the sleeves to prevent substantial relative angular movement of the sleeves and shell around the the sleeve are in effect V 33 and nOtchs barrel. In this way the slot 3! is kept in alignment with the slots 20. As shown in Fig. 2 the inner free ends of the back of the sleeve sections 22 and 23 are formed as teeth 35 and lie between the teeth 33 on the adjacent end of the shell. The shell therefore does not interfere with the contraction of the sections 22 and 23; r

Preparatory to the winding operation the heads 'H and H will be meved approximately totheir.
